Boehly, who also worked seasonally at Camp Denali and North Face Lodge in the park, had been hiking in the backcountry with a co-worker before she was swept down a stream while attempting to cross it Aug. 27.

The memorial will be from 6 p.m. to 9 p.m. at Cafe Flora and will be open to anyone who wishes to join, said Lauren Fior, who sent out notice of the event.

The cafe's owner, Nat Stratton-Clarke, sent a short message with the announcement:

"On Sunday, September 20th, we will close for dinner and spend the evening gathering to remember and celebrate our beloved KC. Bring a vegan or vegetarian dish to share if you are inspired to create something, bring a song to sing if you are inspired to make music, bring a story to share, bring love and togetherness."
